DPRINTF(3) Linux Programmer's Manual DPRINTF(3)NAME
dprintf, vdprintf - print to a file descriptor
SYNOPSIS
#define _GNU_SOURCE
#include <stdio.h>
int dprintf(int fd, const char *format, ...);
int vdprintf(int fd, const char *format, va_list ap);
DESCRIPTION
The functions dprintf and vdprintf (as found in the glibc2 library) are exact analogues of fprintf and vfprintf, except that they output to
a file descriptor fd instead of to a given stream.
NOTES
These functions are GNU extensions, not in C or POSIX. Clearly, the names were badly chosen. Many systems (like MacOS) have incompatible
functions called dprintf, usually some debugging version of printf, perhaps with a prototype like
void dprintf (int level, const char *format, ...);
where the first parameter is a debugging level (and output is to stderr). Moreover, dprintf (or DPRINTF) is also a popular macro name for
a debugging printf. So, probably, it is better to avoid this function in programs intended to be portable.
A better name would have been fdprintf.

Hi,
What is installation package and how to create it?
When we run:

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
Example YAML-File:
